Archer Aviation is acquiring about 300 patents from Lilium, an insolvent eVTOL aircraft manufacturer and former competitor, for €18 million ($21 million) after winning a competitive bid process, the California-based manufacturer announced on October 15. Lilium's insolvency administrator accepted Archer's bid in preference to another made by Europe-based Ambitious Air Mobility Group, which has said the outcome is not in the best interests of creditors and represents a missed opportunity to invest in German industry.
